A medida que las inundaciones aumentan en frecuencia e intensidad, los productos químicos enterrados en los sedimentos de los ríos se convierten en “bombas de tiempo” que esperan activarse.
Researchers identified geochemical tracers for lead and investigated Oklahomans’ concerns at the Tar Creek Superfund site.
Scientists, community groups, and the Clean Water Act are behind Washington, D.C.’s massive project to reduce combined sewer overflows by 96%.
A study of 369 lakes across the Midwest finds that many of them, especially those close to agriculture, have high concentrations of harmful algal bloom-causing cyanobacteria.
By reviewing 44 studies, researchers make a scientific case for regulating agricultural pollution of streams and rivers by implementing conservation practices, including riparian buffer zones.
Poor infrastructure is responsible for tens of thousands of pharmaceutical doses that flow through Baltimore’s streams each year.
Abandoned hardrock mines and climate change cause metals and other elements to leach into streams. They also put rare earth elements into the water, a new study finds.
A handful of new studies analyze the depletion and contamination of groundwater, as well as the effects of climate change—and how communities are responding.
As floods increase in frequency and intensity, chemicals buried in river sediments become “ticking time bombs” waiting to activate.
Agriculture is a key contributor to the algae mats that plague Lake Erie. With so many fertilizers entering the lake, could sediment from the lake floor be used to grow crops instead?
